Abstract
用生活污水处理厂、啤酒厂、木薯厂和糖厂排放的活性污泥有机物质进行发酵，产气有机质配方：有机质中碳(C)＝30，氮(N)＝1，即按C∶N＝30∶1，配制沼气产气有机质原料。当C∶N＜30∶1时，在有机质原料中添加碳铵，满足有机质C∶N＝30∶1条件。
Description
技术领域
本发明所涉及的是一种专用于沼气发酵产气的有机质原料，是供产生沼气原料的创新产品。
技术背景
当今世界不可再生的矿物质能源日趋减少，人们将目光转向次于煤碳、石油、天然气而居第四位的可再生的生物质能源的开发。随着科学技术的进步和对环境保护意识的增强，除了加强对太阳能、水电能、风能的利用外，可利用环境中废弃的生物有机物质作再生能源。这不仅废物利用，保护环境，同时也是开辟新能源的途径之一，符合国家能源开发走自主创新的新型能源发展道路。
沼气是由多种气体成分组成的混合气体，其成分中有甲烷(俗称瓦斯)、二氧化碳、硫化氢、一氧化碳、氢、氧、氮等气体。我国广大农村利用牛粪、猪粪、秸秆等废弃的有机物质作沼气原料已有悠久历史。本发明的创新目的是，利用城乡环境中工农业生产与生活活动排放的废弃有机物质，经过深加工技术处理，专用于产生可燃烧的气体(沼气)，提供城乡沼气生产的有机质原料。
发明内容
利用废弃的有机物质作沼气产气原料，在废弃的有机物质原料中添加适量的碳铵均匀混合，密封堆沤发酵，提供沼气生产所需的有机质原料。
本发明的技术方案
本发明经试验研究用于沼气产气的有机质原料有：生活污水处理厂、啤酒厂、木薯厂和糖厂等厂家生产排放的活性污泥有机质，有机质含水量为自然含水量(约25％)不影响产气量。测定有机质中碳和氮(C、N)含量。当C:N＝30:1时，有机质达到沼气产气有机质量指标要求；当C:N<30:1时，应在有机质中添加适量碳铵，使C:N＝30:1指标要求。C:N>30:1，有利于产气，但不是必须条件。沼气产气的其它条件与技术指标参考相关技术指标，本发明所说的有机质不涉及。
实施技术方案的具体方法(生产工艺)
按下述工艺进行：
1、在选定的上述活性污泥有机质原料中，投入碳铵混合均匀(有机质原料中C：N≥30：1时不需投入碳铵)，用农用尼龙膜复盖堆沤10天。
2、有机质原料包装用双层(内袋和外袋)包装袋包装，或单层包装袋包装。包装后使用密封机封口，严防漏气，袋装产品不宜堆放过高，以防挤压漏气。
Claims (3)
1、产品配方
有机质发酵原料碳与氮比C:N＝30:1
2、产品原料
生活污水处理厂活性污泥、啤酒厂活性化污泥、木薯厂废渣、糖厂污泥(滤泥)、碳铵。
3、生产工艺
在上述活性污泥有机质原料中添加碳铵混合均匀，尼龙膜复盖发酵10天，产品有机质用双层或单层包装袋包装封口不漏气。在有机质中碳与氮比满足C:N＝30:1原料中不需添加碳铵。
